Detailed Description

template<typename WF, typename GlobalVS, typename Result = typename wf_invoke<WF, GlobalVS>::result_type>
struct stapl::paragraph_impl::promotion_resolver< WF, GlobalVS, Result >

Functor that attempts to deduce what input parameter to the workfunction the return value is based on and exactly of what it is a reference to (e.g., reference to some portion of a view element, etc). It then redirects to an appropriate invocation of promote_ref to perform the actual promotion and returns the promoted result.

Primary template used when framework doesn't know how to perform promotion. Unconditionally asserts at compile time.

Template Parameters

WF	The workfunction type passed to task creation.
GlobalVS	The pre-localization view set type.
Result	Computed type representing return type of workfunction is invoked with pre-localization viewset.
